Understanding MPG and WEBM Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

MPEG Video

video/mpeg

MPG is a common file extension for MPEG-1 and MPEG-2 video files, standards developed by the Moving Picture Experts Group. MPEG-1 was the first widely used video compression standard (used in Video CDs), while MPEG-2 became the standard for DVD-Video and digital television broadcasting. MPG files contain multiplexed video and audio streams in a program or transport stream.

Advantages

  • Widely compatible with virtually all media players and hardware devices
  • MPEG-2 provides good quality suitable for DVD and broadcast content
  • Simple, mature format with well-established decoder support

Limitations

  • Significantly lower compression efficiency than modern H.264 or H.265
  • Large file sizes for equivalent quality compared to modern codecs
  • Limited metadata, subtitle, and multi-track support

Common Uses

  • DVD-Video content and disc authoring
  • Digital television broadcasting and cable TV distribution
  • Legacy video archives and Video CD content

Target Format

WebM Video

video/webm

WebM is an open, royalty-free multimedia container format developed by Google, designed specifically for web video delivery. It contains VP8 or VP9 video codecs with Vorbis or Opus audio, and is natively supported by all major web browsers. WebM offers competitive compression efficiency while avoiding patent licensing requirements.

Advantages

  • Royalty-free and open-source with no licensing costs
  • Natively supported in all major web browsers for HTML5 video
  • Good compression efficiency with VP9 codec rivaling H.264

Limitations

  • Limited hardware decoding support compared to H.264/MP4
  • Not widely supported by video editing software for source editing
  • VP9 encoding is significantly slower than H.264 encoding

Common Uses

  • HTML5 web video delivery as an open alternative to MP4
  • YouTube video streaming (VP9 encoded WebM)
  • Royalty-free video content where licensing is a concern
